9 Shocking Things That Happen To Your Brain When You Get A Phone Or Email Notification

"A notification is an interruption or a distraction," Haselberger says. So even if you just glance at your phone for a second, it will break your concentration. And that can have a bigger impact on your brain than you realize.

"Studies show that when we are interrupted it takes our brains on average 23 minutes to return our focus to what we were working on before the interruption," Haselberger says. "Studies also show that we are interrupted every 11 minutes, on average."

Add that up, and it's easy to see how you might feel "busy" and stressed all day long, Haselberg says, while not actually getting anything done. It's why experts recommend putting your phone away, and turning off notifications on your computer, whenever you need to focus.

"We all want to hear the ding of someone responding to us, liking a comment or post, and getting an email we have been waiting for," Dr. Jackson says. But there's an interesting reason why you might feel a pang of excitement, too.

Notifications can trigger dopamine, the "reward" neurotransmitter, to be released in the brain, Dr. Jackson says. And that can make you feel good.

As soon as you see a notification pop up, you may be tempted to read it, even if you're already involved in another task. And that's when multitasking — or, at least, an attempt to multitask — can occur within the brain.

"Most people feel they can multitask but the brain is not meant to do so," Dr. Jackson says. "When you multitask you often do not give your best to both or all tasks you are juggling. And every time you switch back and forth from tasks you also get a rise in cortisol, a stress hormone."

Thanks to the rise in cortisol, it's not uncommon to feel stressed when receiving notifications. In fact, "people who constantly check their alerts have higher anxiety," Dr. Jackson says. "Cortisol levels rise and when this is the brain’s typical presentation [...] it may lead to other mental, emotional, and physical concerns."

Even if you try really hard to multitask, it's not actually possible to do two things at the same time. So keep this in mind when you're out socializing, and see a message pop up on your phone.

As Dr. Jackson says, notifications divert your attention away from what's going on around you, and can make you seem (and feel) cut off. That's why you should "only respond to actual emergencies and step away to do so," she says. "When you return be fully engaged in those who are with you."

Notifications trigger a dopamine release, which not only feels good but can "train" you to take action and respond, psychotherapist Michele Paiva, tells Bustle. Add in serotonin, a chemical that makes you feel valued, as well as endorphins, which can provide a sense of excitement (or anxiety), and you might notice that alerts can cause quite the emotional response.

"You have a chemical reaction that becomes Pavlovian," Paiva says. "You hear the notification and based upon past responses, you feel a response that matches, regardless of the reality." And depending on what you were reading or chatting about, you might even feel angry for no real reason.

"For instance, if you’ve been in a heated political debate or online drama, you may hear a notification and feel anger and stress, even if the notification was that someone liked a positive quote or photo of dessert posted a year ago," Paiva says. "It’s amazing what sound and emotional response can do!"

With alerts coming through on a regular basis, "your brain's dopamine and cortisol pathways can become ‘worn out’ by the constant over-stimulation and you will find yourself more anxious and less happy," Elesa Zehndorfer, PhD, tells Bustle. And that's because cortisol responds most to feelings of uncertainty.

Since you never really know what a notification is for, you can start to feel stressed and burned out, especially if you don't give yourself a break from time to time.

Due to the release of all those aforementioned brain chemicals, and the rewarding feelings you can get from receiving notifications, it's not uncommon to experience tech addiction, Dr. Zehndorfer says. And as is the case with any addiction, this can open you up to some negative mental health implications, including a disruption to family and general life contentment levels and well-being, she says. So be on the lookout for signs you're relying too heavily on your phone, or spending too much time online. And if you need to, there's nothing wrong with reaching out for help.

Notifications can not only be used as a form of distraction, but they also provide a rush of excitement, which can be a way of masking emotional pain. And this works in a similar way to many other addictions.

"All addictions increase pleasure by acting on the brain’s reward system," psychotherapists Lin Anderson, LMHC, M.A., Ed.M and Aaron Sternlicht, LMHC, CASAC, tell Bustle. "Every time you get a 'like' on social media dopamine is released in the brain making you feel good." So if you suspect you're using your phone as an unhealthy coping mechanism, don't hesitate to reach out to a therapist.

Lots of things can occur within the brain when you get a notification, and not all of them are negative or a sign of a problem. But it is interesting to consider what a big impact notifications can have on you, especially since they come rolling in throughout the day — every day.
